Former Watford, West Ham, Newcastle and Norwich boss Glenn Roeder has died aged 65 after a long illness, the League Managers Association has announced.
Roeder, who was a defender during his playing days, began his managerial career with a spell in charge at Gillingham.
He was also a coach in the England set-up when Glenn Hoddle was manager.
The LMA said it was "very deeply saddened" at Roeder's death "after a long battle with a brain tumour".
Roeder began his playing career at Leyton Orient before going on to represent Queens Park Rangers, Newcastle, Watford and Gillingham.
"A cultured defender as a player, he managed with a studious style and was always generous with his time and ideas," said LMA chairman Howard Wilkinson.
"Glenn was such an unassuming, kind gentleman who demonstrated lifelong dedication to the game. Not one to court headlines, his commitment and application to his work at all levels warrants special mention.
"Football has lost a great servant today and our sincere condolences go to Glenn's family and friends."
